Aesthetic reconstruction of soft tissue nasal sidewall loss has an important influence on the appearance of the nose. The unique character of this subunit and the complex relationships with a number of different facial or nasal subunits make the excision of large tumors difficult to manage. Numerous techniques are described in the literature, but a primary reconstruction with a final good resul...

Highly anisotropic dry etching of tungsten silicide and tungsten polycides is required for the realization of submicron low resistance gates and interconnects for use in high performance complementary metal–oxide–semiconductor ~CMOS! and BiCMOS technologies. The current etch chemistries are not anisotropic, i.e., lateral etching of the tungsten silicide takes place which results in undesirable ...

Wound healing is an inherent feature of any multicellular organism and recent years have brought about a huge amount of data regarding regular and abnormal tissue repair. Despite the accumulated knowledge, modulation of wound healing is still a major biomedical challenge, especially in advanced ages. In order to collect and systematically organize what we know about the key players in wound hea...

It has been shown experimentally that the vibration of a tire in the region near the contact patch can be represented by a set of decaying waves, each associated with a particular crosssectional mode. Thus, a tire can be modeled as a lossy waveguide in which decaying waves propagate in the circumferential direction. It may therefore be computationally efficient to analyze tire vibration, especi...

The heat loss and surface temperature of the top surface and sidewall of large-scale floating roof tank is tested by the heat flow meter and surface temperature method. Based on the test data, the heat loss from the top surface is about twice more than that of the sidewall which means the top surface is the weakest insulation part of the floating roof tank. On the surface, the heat loss profile...

A new PE model for solving three-dimensional, forward and backward sound propagation in a cylindrical coordinate system is presented. The model marches a wave field in the radial direction including the azimuthal diffraction effects, and solves for a backscattered field based on a three-dimensional, single scattering approach. A periodic sidewall boundary condition is applied for computations i...

The present paper offers the chance to experimentally measure, for the first time, the internal tire strain by optical fiber sensors during the tire rolling in real operating conditions. The phenomena that take place during the tire rolling are in fact far from being completely understood. Despite several models available in the technical literature, there is not a correspondently large set of ...

Elastic elements such as rail pads, under sleeper pads and under ballast mats are railway components that allow for a reduction in track deterioration and vibrations. And they are furthermore commonly used to obtain an optimal vertical stiffness of the infrastructure. However, the use of elastomeric materials can increase construction costs and the consumption of raw materials. Thus, the utiliz...

Inspired by the idea that bionic nonsmooth surfaces (BNSS) reduce fluid adhesion and resistance, the effect of dimple bionic nonsmooth structure arranged in tire circumferential grooves surface on antihydroplaning performance was investigated by using Computational Fluid Dynamics (CFD). The physical model of the object (model of dimple bionic nonsmooth surface distribution, hydroplaning model) ...
